APCM DA 4082

APCM DA 4082 is 200°F cure modified epoxy prepreg system which can be prepreged on fiberglass fabric, woven Kevlar, or other woven fabrics. In addition to their low temperature cure capabilities, DA 4080 prepregs have excellent flow to allow for vacuum bag cure conditions. DA 4080 is a one sided pre-impregnated system yielding a single sided tack material. DA 4082 is the same system except that both sides of the fabric are coated yielding a double sided tack material. Both prepregs can be used for laminating and honeycomb sandwich construction.

Applications
  • Remove material from cold storage at least 20 hours prior to use to allow for stabilization at room temperature. Keep the material wrapped to prevent moisture from condensing on the adhesive. Cut the prepreg to size, remove the poly separator and apply to part or mold. Remove separator paper. Continue process until the desired number of plies are obtained. When lay-up is complete, the prepreg can be cured in a vacuum bag in an oven or autoclave. Apply at least 10 psi pressure and cure for one hour at 200°F.

Technical Details & Test Data

Cure Cycle

The recommended cure cycle for DA 4080 and DA 4082 Prepregs is one hour at 200°F at 20 psi.

Storage & Handling

Shelf Life
1 Year (0°F in a Sealed Container), 6 Months (40°F), 20 Days (75°F)
Storage

Store material in a contaminate free container and store at O degrees F for extended storage. For shorter storage time requirements store at 40 degrees F, this enables quicker stabilization times.
